i've done the reseating & seems to be my gpu is ok now by i don't know how long it will be so...

two things i would like to let you know which are

1. before the installation of COD Black opps my gpu was ok.... after installation when the i was unable to launch the game from the desktop icon because an error message came saying that d3dx9_43.dll file is missing..... so i searched net about this problem & i found that i have to install few directx updates to fix this up ... so i downloaded DirectX 9.0 Web setup.exe (File version -> 6.0.2600.0 & Compatibility Mode -> Windows xp service pack 3).... then i was able to launch the game but the above said problem started to appear again... not only for this game but also for the other games (e.g EA Cricket 2007 & COD 5 WORLD AT WAR) that I have...

2. I have curently 250 gb SATA hard drive of seagate.. but this is the replaced one... i bought my hard drive in 2009... after 6-7 months it stopped booting & i deposited it in their service ceneter & they replaced it with another one... after 1 yr or so i had to replace that too for the same reason... on average after every 7-8 month i am having a issue which is forcing me to replace my hard drive... if i remember correctly then it is actually the 4th repalcement.... every time i've visited their service center i found there many people coming there with so many issues.... & they are replacing their harddrives instead of repairing it,(i suppose the replacements are nothing but the repaired ones of somebody else's)

so i want to ask you

1.by any chance can this directx installation be the culprit??
2.by any chance is the hard drive harming my gpu and causing the problem to occur repeatedly??

what do you think about these??

thank you in advance.....

Yes this can be the culprit . Why did you install Directx 9 ??? Windows 7 comes with Directx 11 installed by default !!!! and YOU RAN THE DIRECTX 9 IN COMPATIBILITY MODE !!!!??????????? Remove directx 9 first...and then reinstall DirectX 11

Please buy the components from a trusted dealer.....Yes even this can be a culprit.... Whats you power supply wattage ??? If you say this is your 4th replacement ..... then there could problem with your power supply or motherboard.... if you are at a place where you constantly loose electricity... and dont have have a UPS... then ... the sudden loss of power... could cause serious issue with the HDD spindle...

i have stated the reasons in my previous post for which i had to install direct x 9.... the game(call of duty black opps) after installation, could not be launched & it said d3dx9_43.dll file is missing.. then i searched the net... there i found that people are suggesting to install directx 9 which would solve the problem.. so i had to do this...

& after that i was able to launch the game...

please tell me how to uninstall the direct x 9 .... as i'm not getting anything about it in the control panel->program & features ...

how shall i re install directx 11???

what about the d3dx9_43.dll error that appeared after the installation of the game?what shall i do about it if it appears again?

i checked my Directx Version by following your method & it is Directx 11...

but still i wanted to remove the effects of previous directx9 installation if any,so i did the following

i uninstalled my gpu driver... & run driversweeper.... after that i run start->control panel-> programs & features,there i found that all the driver programs were uninstalled except the physx system software was still present in the list... i tried to uninstall it by clicking on it & selected uninstall.. but nothing happened....

so i went to registry & cleared all the entries corresponding to physx... & then finally the physx disappeared from the programs & features list............. after that i've done reinstallation of the gpu driver & performed a clean installation... then i rebooted my system... now i see that there is no physx system software in the control panel-> programs & feature list.....

& since from the reinstallation whenever i'm booting my pc for the first time then after the windows logo appeared my screen is turning black.... & it is haulting there,nothing happens anymore.... so i've to manually reboot... this time after the windows logo the desktop is coming...

Toshiba Satellite P205D-S7438 Crashes While BootingThis has been an ongoing problem I've been having, but has become more and more frequent lately.
